The IBM Quantum Hub at the University of Melbourne offers a complete approach for Members to gain early entry into quantum computing with the support of deep research expertise and the global quantum community.
A new way of thinking
Quantum computing is moving rapidly from proof-of-concept to practical applications in science and business. Developing at a breathtaking pace, we are witnessing a period of evolving interaction between researchers and application developers.
Harnessing the creativity to drive commercial applications will depend on new thinking and new software, developed in parallel with the advancing power and reliability of quantum computing hardware. Early-adopters who drive the development of quantum software in their field will benefit from a strong IP position that will be hard for fast-followers to challenge or replicate.
Australia's only University-based IBM Quantum Hub
Led by Professor Lloyd Hollenberg in collaboration with IBM, the University of Melbourne is the sole university-based IBM Quantum Hub in Australia and New Zealand. The team has worked in quantum computing for some two decades – during this time they have created the blueprint for a full-scale silicon quantum computer and recently set a world record for quantum entanglement on IBM Quantum devices. Through the Quantum Hub, the team is at the forefront of research into practical quantum computing.
In 2018, the team launched the web-based Quantum User Interface (QUI) – a quantum computer simulation environment for software development and training the new generation of quantum programmers.
Quantum computer technology will evolve rapidly, with members of the Quantum Hub at Melbourne positioned to direct that future, working on IBM’s most powerful quantum computers to develop software and expertise for the benefit of their sector and broader society. Professor Lloyd Hollenberg
IBM Quantum is advanced quantum cloud technology – several real quantum computer devices and simulators available for use through the cloud – enabling Fortune 500 companies, startups, national research labs and academic institutions to run experiments and explore use cases.
Foundations of quantum technology
Quantum bits or qubits are quantum mechanical systems, like the state of a single atom or even a microscopic superconducting circuit. Classical computing works with bits, and a bit can only ever be 0 or 1. Qubits can be effectively both 0 and 1 at the same time.
This quality of qubits, called quantum superposition, together with the related phenomenon of entanglement, is where the remarkable increase in computing power begins.
As the number of qubits grow, superposition allows the quantum computer to represent exponentially increasing sets of numbers. To get a sense of what this means, imagine putting one grain of rice on the first square of a chessboard. Now double that number on each square and by the end of the board you’ll have 92 billion tonnes of rice.
Carefully choreographed sequences of quantum logic gates – the quantum software program – manipulate superposition and entanglement across the vast array of quantum information, to expand computational power.
How does IBM Quantum help research and development?
Like the early stages of the digital revolution when no one could imagine how finance or logistics – or the very rhythms of daily life, would be transformed – we can’t yet predict where quantum computing will bring the greatest advantages.
Potential near-term applications for quantum computing
The first business use cases for quantum computing have yet to be determined. They may include, but are not limited to:
- Pharma and Materials, untangling complex molecular and chemical interactions to discover new drugs and materials
- Supply Chain and Logistics, finding solutions for more efficient logistics and global supply chains
- Financial Services, finding new ways to model financial data and isolate risk factors to make better investments
- Artificial Intelligence, enhancing machine learning, hybrid quantum approaches to data classification.
At the Quantum Hub, staff and students are engaged in a range of research projects, spanning fundamentals of quantum information and quantum physics of IBM devices, through to applications in a number of areas.
Quantum User Interface
The Hollenberg group has developed a sophisticated quantum computer simulation tool – the Quantum User Interface (QUI) – for use in research and teaching.
The QUI system is integrated into the following subjects:
